Dolomite has added $100 million in Concrete’s Bitcoin-backed collateral, and the setup lets Concrete borrow against Bitcoin held at BitGo. The arrangement relies on offchain custody settlement for liquidations rather than an immediate onchain sale, and Dolomite’s BTCcx integration is framed as part of a move toward regulated custody in DeFi.

What it means

Concrete’s Bitcoin-backed borrowing sits at the intersection of DeFi lending and institutional custody, with BitGo handling the Bitcoin side of the arrangement. Dolomite’s BTCcx integration shows that this kind of product is being built around regulated custody rather than purely native onchain handling. That places a familiar DeFi use case inside a structure that is closer to how institutional lenders and custodians already operate.

Users and builders working with this setup need to account for liquidation mechanics that do not end with an instant onchain sale. That changes how collateral, custody, and settlement are coordinated when positions need to be resolved. It also means the experience for borrowers and liquidators is different from standard DeFi lending flows. (per thedefiant.io)

The arrangement highlights a trade-off between the self-contained logic of crypto markets and the controls that come with regulated custody. Bitcoin-backed lending in DeFi can expand access for institutions, but it also pushes more of the critical process into offchain infrastructure. That tension matters because it changes where trust and operational risk sit in the stack.
